What is the first step in performing rescue breathing?

The first step in performing rescue breathing involves ensuring that the victim's airway is clear and open. Performing the tongue jaw lift is crucial because it helps to prevent the tongue from blocking the airway, which can occur when a person is unconscious or unresponsive. By tilting the head and lifting the jaw, you create an unobstructed path for air to flow into the lungs when you begin administering rescue breaths.

This initial action is vital, as effective rescue breathing depends on a patent airway to deliver oxygen correctly. If the airway is not managed properly, even the best attempts at rescue breathing may not be effective, rendering subsequent rescue efforts futile. Therefore, understanding this initial maneuver is essential for anyone trained in lifesaving techniques.
